What has not been discussed is that when JT was playing QB the defenses preferred to play the QB first and make him pitch early. He was quite a threat with his wheels and IMO more teams elected to take away the QB run in the triple option and take their chances with the pitch.
It was just the opposite in TM's first year under center as the QB as most teams preferred to force him (TM) to make plays as opposed to slow playing the QB as they did with JT. With a year under his belt at Qb, I expect to see TM distribute the ball more as the defenses are now going to be worried about him keeping the football as they were with JT.
